+# Default layout and custom LED / OLED
+
+Keymap is default 87 qwerty, TKL layout
+
+It have new LED effect:
+- Custom gradient (ported from SirTimmyTimbit code [https://github.com/SirTimmyTimbit/customizable-gradient-effect-for-drop-alt])
+- Diagonal (ported from pleasuretek code [https://github.com/pleasuretek/qmk_firmware])
+- Cool diagonal (ported from pleasuretek code [https://github.com/pleasuretek/qmk_firmware])
+- Knight Rider (ported from jumper149 code [https://github.com/jumper149/qmk_firmware/blob/jumper149/keyboards/dztech/dz65rgb/keymaps/jumper149/])
+- Random breath rainbow (based from daed code [https://github.com/daed/qmk_firmware/blob/master/keyboards/massdrop/alt/keymaps/daed] and modify by me)
+
+And OLED Animation:
+- Bongo Cat (ported from nwii code [https://github.com/nwii/oledbongocat] and modify image animation by me)
+- Waveform Typing (ported from drcforbin code [https://github.com/drcforbin/keyboards] and modify to correct my TKL layout)
+- Galaxy image when pressing FN key (original image [https://www.deviantart.com/rock-bomber/art/Gateway-668850827] and redraw then cut for 128x32 size by me)
+- Redragon Logo when booting up
